LatencyMon -vysoke DPC latency

Příspěvek od Keyzio »

Vysoké DPC latency – dxgkrnl.sys / ntoskrnl.exe – RTX 3060 Ti + Ryzen 7 9800X3D
Poridil jsem si nove soucastky zatim bez GPU a to
CPU: AMD Ryzen 7 9800X3D
MB: ASUS TUF GAMING B850-PLUS WIFI
RAM: Kingston FURY 64GB KIT DDR5 6000MT/s CL30 Beast Black EXPO
GPU: rtx 3060 ti
zdroj: 1000w
Nez jsem napsal sem, tak jsem zkousel jako laik chatgpt s problem, ktery je, ze:

Při hraní hry "New World", jsem mel stabilnich 60fps, 80% vyuziti GPU a prizblizne 4GB/8GB VRAM, a okolo (20-30)% CPU a presto se mi hra trochu trha a do toho se obevuje bzuceni z reproduktoru.
Na zaklade toho jsem si nainstaloval LatencyMon, ktery hned objevil problem a to ze se na core0 pretezuje a ostatni jadra jsou temer nevyuzita, posilam log

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:10:17 (h:mm:ss) on all processors.

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed (WMI): 470 MHz

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 1109,60
Average measured interrupt to process latency (µs): 7,102955

Highest measured interrupt to DPC latency (µs): 1105,10
Average measured interrupt to DPC latency (µs): 2,400633


_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 66,186741
Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Highest reported total ISR routine time (%): 0,002904
Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Total time spent in ISRs (%) 0,002904

ISR count (execution time <250 µs): 189464
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-1000 µs): 0
ISR count (execution time 1000-2000 µs): 0
ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0


_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Highest DPC routine execution time (µs): 100401,478150
Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation

Highest reported total DPC routine time (%): 0,056616
Driver with highest DPC total execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in DPCs (%) 0,154109

DPC count (execution time <250 µs): 2155000
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 569
DPC count (execution time 1000-2000 µs): 19
DPC count (execution time 2000-4000 µs): 0
DPC count (execution time >=4000 µs): 4


_________________________________________________________________________________________________________
REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: system

Total number of hard pagefaults 9483
Hard pagefault count of hardest hit process: 7493
Number of processes hit: 43

Co jsem zkusl na zaklade rad ?
  • pres DDU v nouzovem rezimu odinstalovat gaming verzi ovladace a pak nainstalovat stabilnejsi studio verzi
  • zapnout high performance v napajeni
  • aktualizovat vse i BIOS
  • pres program Msi Utility v3 - zapnut msi rezim u zvukovky a u GPU, a wifi nastavit prioritu
  • zakazat HDMI zvuk z GPU, ktery nepouzivam
  • u virtualni pameti mam: aktualne pridelena hodnota 4GB, ale vlastni velikost je nastavena na 16GB-32GB
  • v BIOS dat Precision Boost Overdrive (PBO) na disable
  • Nastavení pro maximální výkon CPU (bez uspávání jader):
    - Processor idle demote threshold: 100 %
    - Processor idle promote threshold: 100 %
    - Processor performance core parking min cores: 100 %
    - Processor performance core parking max cores: 100 %
    - Minimum processor state: 100 %
    - Maximum processor state: 100 %
kdybych byl ve spatne sekci fora nebo jsem neco duleziteho nenapsal, reknete jsem bezny uzivatel a nerozumim tomu

Muzu se prosim zeptat jestli jsem neco nezvoral.
Jsem ve spatnem topicu, nebo jsem napsal slataninu, ktere nikdo nerozumi, nebo to sem vubec nepatri?
Videl jsem v nazvu diagnosticke programy, tak jsem to dal sem.

Tak týká se to především procesoru... otázka by měla spíš směřovat tam... přesun
